CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 294,987, dated March11, 1884.

Applioation filcd January 15, 1884. (No model.)

To aZZ whom it may concern.-

Be it known'that I, GARRETT B. (hum, of Easton, in the county of Talbotand State of Maryland, have invented certain Improve ments inCar-Couplers, and I hereby declare the following to be a full, clear,and exact description, reference being had to the accompanying drawings,making part of this specification, in which Figure l is a side elevationof my improved coupling. Fig. 2 is a longitudinal vertical sectionthrough the same. Figs. 3 and 4 are details to be referred to.

Myinvention relates to car couplings which engage automatically; and itconsists in certain details of construction and operation, ashereinafter fully described, and specifically pointed out in the claims.

, which the link passes.

end ofthe draw-head and on each side is piv In order that those skilledin the art may make and use my invention, Iwill proceed to describe themanner in which I have carried it out. I

In the said drawings, A is the drawliead, preferably dividedlongitudinally on a vertical central line, the two sections beingfastened together in any convenient manner. The draw-head has the usualflaring opening, into WVithin the hollow oted a drop or weighted lever,H, having a shank,which passes through the wall of the draw-head, andengages at h with a weighted handle, F. Vhen the link passes into thedraw-head, it presses up the levers HH, which rest upon the end of thelink when it has passed into the draw-head and prevent it from dropping.Thelink cis secured or caught automati eally in the draw-head by meansof a curved dog or pin, B, which is secured and pivoted in the draw-headby the bolt 6, upon which it turns as a center. It will be seen,therefore, that the greater weight of the dog B is thrown forward of thepivot, and that the normal position of the dogB is that illustrated inFig. 1. On the upper side of the drawhead I set into the surface aplate,a, provided with a slot or opening, b, and sustained in position bytwovertical bolts or rods, 1) b, one 011 each side of the draw-head,passing through vertical holes in the draw-head, whereby the plate a isallowed a free vertical movement, for a purpose hereinafter set out;Immediately behind the plate a the draw-head has a slot, 9, cut in it,in a line with slot b in plate a, and of about the same dimension. Thesetwo slots 1) and 9 receive and retain the ends t and'z" of the dog B, tosecure the coupling-link. Pi voted to the outside of the draw-head, atd, is a lever, (l, the lower end'of which rests beneath one of the rodsb, and the upper end being provided with a foot-piece,p, wherewith tooperate thelever.

The operation is as follows: The device be.- .ing in the conditionillustrated in Fig. 1, the link 0 is passed into the draw-head, when theweighted levers H H hold it in position. Vhen the cars come together,the link is forced into the draw-head until the end strikes the dog Babove the pivot e, and pushing back the end i the plate a is raised bysaid end until the end t" registers with the slot 9. At the same timethe end t of the dog has passed beneath slot 1), and the plate a dropsand securely holds the ends of the coupling-dog, thereby completing theoperation of coupling. To uncouple, the end 1) of lever O is pushedforward, the lower end raises belt I) and plate a, and releases the endsof the dog, so it drops forward and downward and releases the link.

Having thus described my invention,what I desire to secure by LettersPatent is 1. The draw-head, in combination with the independent weightedlinksustaining levers H F, for the purpose set forth.

2. The curved dog B, pivoted behind the center, in combination with thevertically-sliding plate a, provided with vertically-moving rods 12 12,substantially as and for the purpose set forth.

3. The car-coupling herein described, having the draw-head A, curved dogB, pivoted behind the center, the sliding plate a, provided with slot 1)and rods b I), lever 0, having footpiece 19, and weighted levers H F,all 0011- structed, arranged, and operated as set forth.

In testimony whereof Ihereunto set my hand this the 3d day of January,A. D. 1884..
